Floor response spectra–oriented acceleration mitigation of base-isolated structures with rate-independent damping

Engineering structures accommodating acceleration-sensitive non-structural equipment exhibit an intrinsic incompatibility in seismic demand control, as base isolation effectively suppresses inter-story drift, whereas the introduction of linear viscous dampers to restrain isolator...

Productivity loss associated with type 2 diabetes in China: the trend and projection from 1990 to 2050

Background: Type 2 diabetes (T2D) has become increasingly prevalent among young adults in their prime working years. This study aimed to estimate the productivity-adjusted life years (PALYs) loss associated with T2D among working-age Chinese adults from 1990 to 2021, with project...

Teachers' AI use and student learning outcomes in higher education: The roles of learning engagement and teacher AI literacy

Purpose As generative artificial intelligence (AI) becomes increasingly integrated into higher education, teachers are playing a central role in transforming AI technologies into educational value. However, empirical evidence regarding whether and how teachers' AI use improves st...

Association between in-hospital changes in estimated plasma volume status and worsening renal function in patients with acute heart failure

Worsening renal function (WRF) during treatment for acute heart failure (AHF) has context-dependent clinical implications. Estimated plasma volume status (ePVS), calculated from hematocrit and body weight, may complement decongestion assessment. We evaluated the association betwe...

Optimizing citrus deficit irrigation across diverse contexts to balance yield, fruit quality, and water productivity: A global meta-analysis

Citrus is the largest fruit category globally and holds significant economic value. Scientifically regulated deficit irrigation (DI) serves dual functions of water conservation and quality regulation. The effects of DI on citrus yield, quality and water productivity (WP, the rati...

Evolution and paradigms in ion channel and cardiac remodeling

Objective: This study aims to conduct a bibliometric analysis of the literature on the role of ion channels in cardiac remodeling. Methods: Articles on ion channels and cardiac remodeling from 1979 to 2024 were retrieved from the Web of Science Core Collection (WoSCC). Bibliometr...

Genomic Diversity of the Endangered Guinan Toad‐Headed Lizard and Its Conservation Implications

ABSTRACT The Guinan toad‐headed lizard, Phrynocephalus guinanensis , is a small reptilian species restricted only to the Mugetan Desert on the northeastern corner of the Qinghai–Xizang Plateau. This species faces endangerment due to its extremely narrow distribution range, combin...

Sandwich structured Ω-shaped fiber optic-based sensor with dual signals for simultaneous temperature and refractive index detection

Measurements of refractive index (RI) and temperature play a vital role in a wide range of applications. Nevertheless, cross-sensitivity remains a major obstacle when RI and temperature need to be measured simultaneously. In this study, a novel sandwich structured Ω-shaped fiber...

Polarization-controlled ultrafast carrier dynamics in sliding ferroelectrics revealed by machine learning-accelerated nonadiabatic dynamics simulations

Sliding ferroelectrics offer a unique pathway to electrically reconfigurable polarization at the atomic scale, offering compelling opportunities for ultralow-power optoelectronic devices. Yet, despite rapid advances in materials discovery, the fundamental question of how polariza...

Spatiotemporal delivery of immune-synapse-stabilizing NK cells for postoperative tumor therapy

Natural killer (NK) cells eliminate target cells by forming an immunological synapse (IS). Here, we equip NK cells with multivalent galectin-3 binding polymers that resemble prehensile “arms” to mechanically reinforce the NK-to-target tumor cell connection. These armed NK cells (...

Ambidextrous innovation leap and patent abandonment: A resource orchestration perspective

Patent abandonment can be conceived as a deliberate approach to orchestrate and streamline patent assets, which is often shaped by firms' innovation strategies. This study conceptualizes ambidextrous innovation leap as a strategic reconfiguration of innovation trajectories that r...

Conformation-Engineered Silk Fibroin Microspheres: Controllable Fabrication toward Precision Biomedical Platforms

Abstract Polymer microspheres have garnered significant interest in biomedical applications owing to their tunable size, high specific surface area, and high drug-loading capacity. Silk fibroin (SF), a natural protein with excellent biocompatibility, controllable biodegradability...

The association between perioperative oral care and adverse clinical events after complex cardiac surgery in children

Oral health is closely linked to various clinical complications, and maintaining good oral care has become one of the important interventions to reduce the risk of adverse clinical events. However, the association of oral health care with sepsis and cardiac function remains contr...

Sprayable EGCG-Grafted Alginate Hydrogels Embedded with Platelet Exosomes: Functional Synergy of Immunomodulation and Angiogenesis for Accelerating Burn Wound Healing

Abstract Burn wounds were often entrapped in inflammatory cascades and highly vulnerable to bacterial infection. Meanwhile, accumulated necrotic tissue and impaired vessels further aggravated local ischemia, thereby impeding the wound healing process. Herein, a sprayable hydrogel...

Mobility Control and Solid–Liquid Interface Interaction Mechanisms of Psyllium Gum-enhanced CO2 Foam

Abstract Efficient mobility control is essential for foam-enhanced CO2 flooding and storage, yet the adsorption of chemicals in reservoirs can cause foam destabilization and mobility-control loss. This study investigates the mobility control and solid–liquid interfacial mechanism...

Knowledge and attitudes of nurses and nursing students about Alzheimer’s disease: a systematic review and meta-analysis

With the global aging population, the burden of Alzheimer’s disease (AD) is increasing, underscoring the critical need for competent AD care. While previous studies have explored nursing personnel’s knowledge of and attitudes toward AD, a comprehensive synthesis across diverse cu...

Association between circulating tumor DNA and the prognosis of solid tumor patients receiving neoadjuvant therapy: a meta-analysis
